TECHNICAL FIELD
[0001] The present application relates to the technical field of air conditioning equipment, in particular to an air conditioner indoor unit capable of differential temperature regulation. BACKGROUND
[0002] At present, existing air conditioners generally have only one air outlet system, and the air outlet of the air conditioner indoor unit is generally directly aimed at the head or chest and abdomen of the human body for air outlet. In particular, the air outlet mode of the upright cabinet type air conditioner will make the user feel strong wind, and long-term exposure of the head or chest and abdomen to the wind will reduce the comfort of the user and is not conducive to the health of the user.
[0003] In view of the problem that the air conditioner directly blowing the head or chest and abdomen of the user will not bring high comfort, air conditioners that can avoid blowing the head or chest and abdomen of the human body have appeared on the market, such as a cabinet type air conditioner disclosed in Chinese patent application No. CN202020417440.8. The cabinet type air conditioner is mainly designed with two air outlets that do not directly blow to the head or chest and abdomen of the user. One air outlet is arranged at the top of the body to realize air supply to the area above the head at a distance, and the other air outlet is arranged at the bottom of the body to realize air supply to the area near the legs and feet of the human body.
[0004] The double-area air supply structure of the cabinet type air conditioner can achieve the purpose of avoiding direct blowing of the air conditioner wind to the head or chest and abdomen of the human body. However, the air outlet temperature of the two air outlets of the double-area air supply structure is basically unchanged, and the bottom air outlet will inevitably blow to the legs and feet of the human body. In particular, when the fast cooling mode is started, the low-temperature cold air directly blows to the legs and feet of the human body, which will still reduce the comfort of the user, especially when the user is an old person, the influence on comfort is particularly obvious, and at the same time, this is obviously not conducive to the health of the user. That is to say, the isothermal air supply form of the existing air conditioner with a double-area air supply structure still has the problem of low comfort and is not conducive to the health of the user. SUMMARY
[0005] In order to overcome at least one of the defects of the prior art described above, the purpose of the present application is to provide an air conditioner indoor unit capable of differential temperature regulation to solve at least one of the technical problems mentioned in the prior art: the isothermal air supply form of the existing air conditioner with a double-area air supply structure still has the problem of low comfort and is not conducive to the health of the user.
[0006] The technical solution of the present application is as follows:
[0007] The application discloses a temperature-difference-regulated air conditioner indoor unit, which comprises a machine body provided with a supply air outlet, a first air outlet and a second air outlet, a first air supply cavity is arranged between the supply air outlet and the first air outlet, and a second air supply cavity is arranged between the supply air outlet and the second air outlet; and a heat exchanger for heating or refrigerating the gas entering the machine body from the supply air outlet, wherein the heat exchanger is arranged in the machine body, and the temperature-regulating assembly is further arranged on the heat exchanger.
[0008] That is to say, the temperature-regulating assembly can be connected to and regulate the flow size of the refrigerant flowing into the first heat exchange area, so that the heat exchange power of the first heat exchange area can be regulated, and of course, the temperature-regulating assembly can be connected to and regulate the flow size of the refrigerant flowing into the second heat exchange area, so that the heat exchange power of the second heat exchange area can be regulated.
[0009] In addition, the temperature-regulating assembly can be connected to and comprehensively regulate the flow size and flow direction of the refrigerant flowing into the first heat exchange area and the second heat exchange area, so that the heat exchange efficiency of the first heat exchange area and the second heat exchange area can be comprehensively regulated, the temperatures of the air flowing through the first heat exchange area and the second heat exchange area and being heat-exchanged are different, and the purpose of temperature-difference regulation is achieved.
[0010] The temperature-difference-regulated air conditioner indoor unit can be used in the following manner: air enters the machine body from the supply air outlet and flows through the heat exchanger to be heat-exchanged. The heat exchanger is divided into the first heat exchange area and the second heat exchange area by the partition, and the temperature-regulating assembly is connected to the heat exchanger to regulate the heat exchange power of the first heat exchange area and the second heat exchange area. Thus, under the action of the temperature-regulating assembly, the air flowing through the two heat exchange areas to be heat-exchanged forms a temperature difference, so that the air conditioner indoor unit provided with the first air outlet and the second air outlet can achieve the purpose of temperature-difference regulation. Therefore, when the temperature-difference-regulated air conditioner indoor unit is actually used, the heat exchange efficiency of the heat exchange area corresponding to the air outlet blowing to the human body is controlled, so that the temperature of the air flowing through the heat exchange area to be heat-exchanged can be adapted to the temperature of the human body, and the purpose of improving the user comfort is achieved, so that the adverse effects on the health of the user are reduced.
[0011] By the indoor air conditioner, the air supply temperature of the air supply port blowing to the human body is kept in a more suitable temperature range by the regulating effect of the temperature regulating assembly on the heat exchange efficiency of the heat exchange area, so that the user's comfort can be improved. Of course, in actual use, the air supply temperature of the two air supply ports can also be regulated according to the specific needs of the user to achieve the purpose of meeting the comfort requirement and achieving rapid cooling or rapid heating, for example, when rapid cooling is required, the heat exchange power of the heat exchange area corresponding to the air supply port not blowing to the human body is increased by the temperature regulating assembly, so that the air after heat exchange of the heat exchange area has a lower temperature. As a result, there is a large temperature difference between the air conditioner air from the two air supply ports, and convection occurs between the air in the first air supply area and the second air supply area in the same indoor space, so that rapid mixing and cooling are achieved. The flow of indoor air is enhanced, which is obviously beneficial to rapid cooling or rapid heating.

By regulating the first control valve, the flow rate of the refrigerant flowing into the first heat exchange area can be regulated, and the heat exchange efficiency of the first heat exchange area can be adjusted. If the first control valve is closed, the refrigerant flowing through the first inlet pipe can be blocked, so that the refrigerant can flow into the second heat exchange area, and the temperature regulating assembly can regulate the flow direction of the refrigerant.
[0014] Further, the temperature regulating assembly further comprises a second control valve arranged on the second inlet pipe. The second inlet pipe serves as a pipe for allowing refrigerant to flow into the second heat exchange area. By regulating the second control valve, the flow rate of the refrigerant in the second heat exchange area can be regulated, and the heat exchange efficiency of the second heat exchange area can be adjusted. By regulating the first control valve and the second control valve, the flow rate and flow direction of the refrigerant in the first inlet pipe and the second inlet pipe can be regulated.
[0015] Further, the first heat exchange area is provided with a first outlet pipe for allowing refrigerant to flow out of the first heat exchange area; the second heat exchange area is provided with a second outlet pipe for allowing refrigerant to flow out of the second heat exchange area; and the first outlet pipe and the second outlet pipe are both connected to the outdoor compressor to achieve the purpose of refrigerant return.
[0016] Further, the partitioner comprises a first fan and a second fan; the first fan is arranged between the air supply port and the first air outlet, and the air sucked by the first fan flows through the area of the heat exchanger to form a first heat exchange area; the second fan is arranged between the air supply port and the second air outlet, and the air sucked by the second fan flows through the area of the heat exchanger to form a second heat exchange area; the first fan and the second fan are used to form flowing air-conditioning air in the machine body; only through the centrifugal suction of the first and second fans, the air flowing through the heat exchanger can be naturally divided, and thus, by adjusting the refrigerant flow of the two heat exchanger areas through which the two groups of air flow, respectively, the corresponding heat exchange efficiency of the two heat exchange areas can be controlled, so as to achieve the purpose of temperature difference air supply.
[0017] At the same time, by adjusting the power of the first fan and the second fan, respectively, the air power of the two air outlets can be independently adjusted, so as to better meet the use requirements of users and improve the comfort of users.
[0018] Further, the partitioner further comprises a partition plate arranged in the machine body, and one side end of the partition plate contacts the heat exchanger to divide the heat exchanger into a first part and a second part; the space between the first part and the first air outlet forms a first air supply channel, and the first fan is arranged in the first air supply channel; under the isolation of the partition plate, the air flowing through the first part will be sucked by the first fan, so that the first part can directly form the first heat exchange area; the space between the second part and the second air outlet forms a second air supply channel, and the second fan is arranged in the second air supply channel; under the isolation of the partition plate, the air flowing through the second part will be sucked by the second fan, so that the second part can directly form the second heat exchange area.

[0021] Further, the partition plate is provided with a vent; the partitioner further comprises an opening and closing plate for opening and closing the vent, and the opening and closing plate is movably arranged on the partition plate.
[0022] Therefore, in some use cases, the vent is opened by controlling the opening and closing plate to move on the partition plate, that is, the first air supply channel and the second air supply channel are connected, at this time, the air conditioner air from the first air outlet and the second air outlet is substantially the same in temperature, which can meet the purpose of mixed air outlet with the same temperature to adapt to the air outlet requirements of different users.

For the convenience of description, the air supply area corresponding to the first air outlet 102 is defined as a first air supply area, and the air supply area corresponding to the second air outlet 103 is defined as a second air supply area. Figures 1-4 and Figure 6 A first air supply cavity 104 is arranged between the supply air outlet 101 and the first air outlet 102, and a second air supply cavity 105 is arranged between the supply air outlet 101 and the second air outlet 103. The first air supply cavity 104 and the second air supply cavity 105 provide flow space for air flowing to different areas in the body 1. A heat exchanger 2 is arranged in the body 1 and corresponds to the position of the supply air outlet 101 to improve the heat exchange fluency. The heat exchanger 2 is further provided with a partition 3 and a temperature-regulating assembly 4 for regulating the flow size and flow direction of refrigerant in the heat exchanger 2. The partition 3 is arranged to divide the heat exchanger 2 into a first heat exchange area 201 and a second heat exchange area 202. The first heat exchange area 201 is arranged on the first air supply cavity 104, and the second heat exchange area 202 is arranged on the second air supply cavity 105. The temperature-regulating assembly 4 is connected to the first heat exchange area 201 and / or the second heat exchange area 202. That is, the temperature-regulating assembly 4 can be connected to and regulate the flow size of refrigerant flowing into the first heat exchange area 201 to regulate the heat exchange power of the first heat exchange area 201. Of course, the temperature-regulating assembly 4 can also be connected to and regulate the flow size of refrigerant flowing into the second heat exchange area 202 to regulate the heat exchange power of the second heat exchange area 202.

[0040] The air conditioner indoor unit of the embodiment can be controlled at different temperatures.

For example, when rapid cooling is required, the temperature adjusting assembly 4 increases the heat exchange power of the heat exchange area corresponding to the air outlet not blowing to the human body, so that the air after heat exchange in the heat exchange area has a lower temperature. As a result, there is a large temperature difference between the air conditioner air from the two air outlets, and convection occurs between the air in the first air supply area and the second air supply area in the same indoor space, achieving the purpose of rapid mixing and cooling.

For the dining table close to the air conditioner, the temperature of the air conditioner air of the close-range air supply outlet can be adjusted to a higher temperature to meet the specific temperature requirement of the close-range area, and the temperature of the air conditioner air of the long-distance air supply outlet can be adjusted to a lower temperature to meet the overall temperature adjustment requirement of the entire space.
[0064] Preferably, referring to Figure 4 and Figure 6 , the heat exchanger 2 is provided with a ventilation port 207, and the second air supply channel 105 is communicated with the second air outlet 103 through the ventilation port 207 to form a complete air flow path.
[0065] Working principle: according to the specific needs of the user, for example, when rapid differential temperature refrigeration is required, the first fan 6 and the second fan 7 are started to make the air outside the body 1 enter the inside of the body 1 through the air supply port 101, and pass through the first heat exchange area 201 and the second heat exchange area 202, and at the same time pass through the regulation and control of the temperature regulation assembly 4, so that the temperature of the air passing through the first heat exchange area 201 is different from the temperature of the air passing through the second heat exchange area 202. After that, under the action of the first fan 6 and the second fan 7, the air conditioner air after heat exchange of the first heat exchanger area 201 and the second heat exchange area 202 passes through the first air outlet 102 and the second air outlet 103 respectively, realizing the purpose of differential temperature air supply in different areas.
[0066] To sum up, the indoor unit of the air conditioner with differential temperature regulation can realize the purpose of differential temperature air supply by partitioning the heat exchanger into the first heat exchange zone and the second heat exchange zone through the partition, and regulating the heat exchange power of the first heat exchange zone and the second heat exchange zone by the temperature regulating assembly.
